First I began by colecting the materials:
- a small stone,
- slate pieces,
- piece of resin mold overcast (from my Forge World Crisis Suit - not necesary)
- piece of styrofoam
- some small resin pieces on the 40k basing kit,
- fine sand
- PVA glue
- Super glue
- Hobby knife
I shaped the styrofoam in a more or less round disc and trimmed the edges into a wedge
Then glued the styrofoam at the center with PVA Glue and then used the pva to glue the rock, the resin and slate pieces, once they where placed I grabbed a spry can of paint and pressed the trigger on a small circle that melted the stirofoam and let it dry for a while, for a more specific how to you can check the +Teri Litorco video on Terrain Part 1
After that I covered the surface of the base with PVA glue, I made sure to cover the styrofoam that remained after the melting process was completed, it is critical as it will prevent more melting.
the last stage was the painting: I started by drybrushing scorched earth but any dark brown will do, after that I drybrushed vomit brown
I left the center of the crater mostly black and then I started to drybrush a dark grey on the stones and th ceter of the crater only, and started to pick some details like the spent cartridges with some brass and the chaos helmet, on the tubes I used screaming bell and astronomican grey on the concrete slabs, when that dried I used a wash of ogryn flesh on the slabs and somo stones followed by a bit of devlan mud. I also glued some static grass and painted some green here and there.
while it dried I painted the gem on the cross at the base
